Devicetree动态解析器说明 | ||
======================== | ||
|
||
本文描述了内核内DeviceTree解析器的实现,它位于drivers/of/resolver.c中。 | ||
|
||
解析器如何工作? | ||
---------------- | ||
|
||
解析器被赋予一个任意的树作为输入,该树用适当的dtc选项编译,并有一个/plugin/标签。这就产 | ||
生了适当的__fixups__和__local_fixups__节点。 | ||
|
||
解析器依次通过以下步骤工作: | ||
|
||
1. 从实时树中获取最大的设备树phandle值 + 1. | ||
2. 调整树的所有本地 phandles,以解决这个量。 | ||
3. 使用 __local__fixups__ 节点信息以相同的量调整所有本地引用。 | ||
4. 对于__fixups__节点中的每个属性,找到它在实时树中引用的节点。这是用来标记该节点的标签。 | ||
5. 检索fixup的目标的phandle。 | ||
6. 对于属性中的每个fixup,找到节点:属性:偏移的位置,并用phandle值替换它。 |
